The Lowdown
Alright, Rusty here, checking the pulse at Lakey Pipe (West Sumbawa). This reef is about to get a solid run of SW groundswell, and it’s looking good.
Water temp is about 80°, dead average for the season. No weirdness there.
The first big pulse hits Wednesday afternoon: 2.5m swell, 18-second period, energy at 3839. That’s serious, long-period groundswell, and the wind is a clean ESE cross-off at 15 km/h. This is the standout early session – powerful, clean, and barreling. Only for experienced surfers, that long period will make the sets meaty.
Thursday morning is even bigger: 3.0m, energy 4228, still clean cross-off. That’s expert territory. Afternoon drops to 2.5m, still clean.
Friday through the weekend, we’re locked in steady: 2.1m to 2.4m SW swell, 15 to 17-second period, cross-off winds. Friday morning is the standout: 2.2m, 15 seconds, clean, energy 2286. Beautiful.
A small dip around Tuesday 25th morning drops to 1.6m, but the afternoon picks back to 1.8m. Still good.
Then Friday 28th morning, another solid pulse: 2.4m, 17 seconds, energy 3046, light breeze. That’s a classic session.
The long-range standout is Tuesday 1st September: 2.5m, 18 seconds, energy 4030, light offshore. That’s the best of the second week. It holds through the 2nd.
Crowds are often here, but with this quality, it’s worth it.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
